BUMPER FOR VEHICLES.

I Application filed April 23, 1926. Serial No. 104,035.

My invention relates to bumpers for ve hiclcs and has for its general object to proride a bumper which is simple and sturdy in construction, cheap to manufacture, etficient and durable in use, and attractive in appearance.

One of the principal objects of my invention is to provide an improved form of spacing members between parallel impact bars and means for securing the impact bars, the spacing members, and the supporting bar or arms together.

Still another ob'ect of my invention is to provide improve means for securing a block formed of rubber or other flexible material in position between the impact section of the bumper and the supporting means therefor.

Other and further objects and advantages of my improved bumper will become apparent from the following description, taken in conjunction with the accompanying drawing.

In the drawings, Fig. 1 is a perspective view of a bi'imper embodying my invention; Fig. 2 is a rear elevation of one end of the bumper showing the eye of the supporting member in section; Fig. 3 is a transverse section taken on the line 3-3 of Fig. 2; Fig. 4 is a horizontal section taken through one end of the bumper as on the line 4-4 of Fig. 2; Fig. 5 is a transverse section taken through the center of the bumper as on the line 55 of Fig.1; Fig. 6 is a fragmentary rear elevation of the central portion of the bumper with the middle of the supporting bar broken away; Fig. 7 is a perspective View of one of thespacing plates or blocks; Fig. Sis a rear view of the device adapted to carry a trade-mark or ornamental design, and Fig. 9 is a perspective view of thecentral spacing block.

The impact section of my bumper com- -p prises two parallel like impact bars 10 and spacing lates or blocks 12 between their ends. T e impact bars are formed of sheet metal and are channel-shaped in cross-section, with the outer flanges 11 and narrower inner flanges l1 extending the length ofthe bars. Each spacing block12 (Figs. 2,-3, 4 and 7) is formed of sheet metal and the inner vertical end of the block is provided with an inwardly extending flange 13. The spacing blocks'12 are curved longitudinally so that they are concentric with the curved ends of the impact bars 10. Projecting oppositely from the horizontal edges of each block are integral projections forming portions 14 in the )lane of the block and rearwardly exten ing ears 15, which are provided with apertures 16. As best shown in Figs. 2 and 4, the inner flanges 11" with recesses 17 which are substantially as wide as the portions 14 and the forward edges of the recesses are slightly curved (Fig. 4) so that the forward of the projecting portions 14 engage snugly thereagainst. The horizontal e ges of the Spacing blocks on either side oi the portions 14 contact against the inner flanges ll 'of the impact bars, as best illustrated in Fig. 2.

In order to secure these parts together, I provide bolts 18 which projectthrough apertures 19 (Fig. 3) in the outer flanges 11 of the impact bars 10 and through the 21, intermediate straight portions 22,'and

curved portions 23 provided at their ends with integral eyes 24 (Figs. 2 and 4). When the bumper parts are assembled, the bolts 18 project through the eyes 24, which are positioned betwen the ears 15 of the res ective spacing blocks 12. It will be noticed that the distance between the ears "15 of each spacing block is greater than the distance between the adjacent sides of impact bars for the purpose of accommodating the eyes 24, the supporting member also being wider than the space between the imact bars. The nuts on the lower ends of the bolts are screwed tightly on the bolts, the flanges 11 being slightly yieldable, in order that the ears 15, which are somewhat flexible, may-be firmly pressed by the collars 20 against the, edges of the eyes 24 to prevent all loose play and rattle between the eyes 24 and the ears 15. v It will be noted that the bolts 18 which are employed to secure the impact bars and the spacing blocks together are also emloyed to connect the supporting bars to the impact section, thus affording common of the impact bars are provided curved sides means for performing these functions with attendant cheapness in construction and simplicity in design As the portions 14 of the spacing blocks engage the curved edges of the recesses 17, the spacing blocks are prevented from having any rotational play or movement,- and the shocks received by the impact bars when striking an obstruction are partly imparted to the spacing blocks so that the entire force or blow is not imparted tothe ends of the bolts 18 through the outer flanges 11 of the impact bars. The impact bars are held snugly against the horizontal edges of the spacing blocks so that when the impact section of the bumper is viewed from the front it gives the appearance of an impact section having the two impact bars and the spacing blocks formed of a single piece of sheet metal.

At the center of the impact bars, I provide a plate or disk 26 (Figs. 5 and 8) to the front face of which a trade-mark or suitable artistic design or insignia may be applied. The rear side "of the disk 26 has asquare portion 27 which is adapted to fit snugly between the central portions of the impact bars. The disk 26 is held in position by means of a screw 28 which projects through a block 29 and at its forward end is screw threaded into an opening in the disk. .The block 29 is preferably formed of sheet metal cut and bent to provide forwardly extending vertical and horizontal flanges 36 and slots 37 at the corners. The

vertical width of the slots 37 is substan-v tially the same as the thickness of the flanges 11 of the block 29 rests against the rear edges of the inner flanges 11 of the impact bars and carries a rubber block 30 having a central opening 31 to accommodate the head 32 of the screw 28. As the flanges 11 1 fit snugly in the slots 37 it will be seen that the vertical and horizontal flanges 36 space the impact bars apart and prevent any vibration between them. In order to firmly hold the block 30 in position, I provide a cup or thimble-shaped member 33 which'is held in place against the plate 29 by the head 32 of the screw 28 and which is provided with an outwardly-extending flange 35 engaging against an annular shoulder formed in the" central opening of the rubber block. This affords a simple and cheap means for securing the block 30 in posi tion and at the same time the screw secures the plate 29 and the member 33 in fixed relation. As shown in Fig. 5, the center of the arch 21 of the spring supporting bar contacts with the rear side of the rubber block to eliminate rattle and undue vibration and at the same time strengthens the middle of the impact section.
